1. New mechanism of penduous needle with fast sewing speed, 2800SPM motor, 50MM pulley, 1.5 times higher efficiency.
2. Fully automatic lubrication assures less friction on machine parts, which increases the life of the machine, and lowers the fee for repairing.
3. The lower shaft transfers the movement to the axle of the rotary shuttle.
4. Double the size of a large bobbin reduces the frequency of changing the bobbin thread; and which also rises up sewing efficiency.
